Not scientific, but wanted a general idea how well these Waitley batteries would handle compared to my genuine Milwaukee M12 3Ah battery. All batteries were purchased at the same time, but no idea how old they actually are. I also don't know the specifics of the batteries so I don't know what the curves look like, but here are the results. As a note, my application only draws about 3A so these batteries will work for me. Fully charged with genuine Milwaukee charger. Fluke 36 clamp meter Fluke 117 Multimeter Load, 90W 12VDC radiator fan Battery 1 Milwaukee M12 3Ah *Fully charge *10 minute rest Voltage before load: 12.21VDC Initial Load: 7.9A Load at 120 seconds: 7.2A Time: 120 seconds *10 Minute rest Voltage after load: 11.98VDC ~Voltage drop: .23VDC ~Amperage drop: .7A Battery 2 Waitley 3Ah *Fully charge *10 minute rest Voltage before load:12.39VDC Initial Load: 7.5A Load at 120 seconds: 6.8A Time: 120 seconds *10 Minute rest Voltage after load: 11.92VDC ~Voltage drop: .47VDC ~Amperage drop: .7A Battery 3 Waitley 3Ah *Fully charge *10 minute rest Voltage before load:12.25VDC Initial load: 7.2A Load at 120 seconds: 6.7A Time: 120 seconds *10 Minute rest Voltage after load:11.83VDC ~Voltage drop: .42VDC ~Amperage drop: .5A For the price of a $70 Milwaukee M12 3Ah and ~$10 each for these, they a suitable alternative. Edit: Tested again. Battery 2 Waitley 3Ah *Not fully charged *10 minute rest Voltage before load:12.1VDC Initial Load: 6.1A Load at 12 minutes: 5.3A Time: 12 minutes *10 Minute rest Voltage after load: 10.7VDC ~Voltage drop: 1.4VDC ~Amperage drop: .8A

This is the second set I’ve purchased. It’s nice to have a second set on the charger, while using the other set. The fit is decent and stay in the tool, but not quite as good as OEM, but at this price point, I’ve been more than happpy with charge speed, durability and functionality.

Don't know for sure if they last as long as the originals, but at this price I can have a box full in my truck ready to keep me warm on the coldest days.

Snaps in like the Milwaukee battery ,will see how long the battery last.

These batteries do fit into my M12 drill, but have some play. The biggest disappointment is they die very fast. Nowhere near a true 3.0Ah Milwaukee brand battery. You get what you pay for. If i were to get new ones sent to me to replace to ones i have, i'd try again but expect the same results. Either save your money and buy authentic Milwaukee batteries, or get these and expect to spend more time charging than using.
